'To all whom 'it 'may concern:

Be it known that I, ARTHUR N. Vvns, a citizen of the United States,residing at Youngsville, in the county ot'lVari-en and State ofPennsylvania, have invented a new und useful Furniture-Joint for W'oodenStructures, of which the following is a specification.

This invention has relation to joints tor wooden structures such asfurniture and the like and it consists in the novel construction undarrangement of its parts as hereinafter shown and described.

rlhe object ot' the invention isto provide a simple and eiiectivemeansfor joining together apposed pieces of wood ot a structure in suchmanner that they Will be iirmly held together without danger ofsplitting.

T he means constituting the joint consists of a hollow tubular memberhaving the inner surfaces of its ends chamfered, whereby, edges areformed at the outer surfaceof the said member. Annnlar mortises arecutin the upposed pieces of Wood and the end portions of the tubularmember are inserted in and seated in the said mortises. The don'el.screw or pin passes longitudinally through the tubular member undengages the apposed pieces of wood. The said tubes may be trulycylindrical in contour or its periphery may be provided with spirallydisposed corrugations which afford friction surface tor entering thegrain o'f the Wood.

In the accompanying drawing z-Figure l is .a sectional View of apposedpieces of` Wood secured together by the oint, and illustrating a spokeor leg connected with the said ,pieces of Wood at the point of juncture.

Fig. 2- is a sectional view of apposed pieces,

of wood showing a modified` form of joint. Fig. 3 is a sectional View ofapposed pieces of wood showing a modified form of the tubular member ot'the joint. Figs. 4, 5, 6 and 7 are detailed sectional views of othermodified forms of the joint.

lThe means for connecting the apposed pieces of wood together consistsot' a tubular sleeve l which is inserted at its opposite end portions inthe said pieces of wood. Circular mortises 2 having been previously cutin the Wood for the-reception of the said sleeve. The inner end portionsof the sleeve are chamfered, as at 3, and terminate in edges' located atvthe outer surfaces of the said sleeve. .;'viheseedges are adapted to bedriven into, and securely seated, in the inner end portions of themortises 2.

As illustrated in Fig. l of the drawing, a doWel pin 4 passes centrallyand longitudinally through the sleeve 2 and is embedded at its endportion in the apposed pieces of Wood which are joined together. rThesaid dowel pin also passes through the tcnon of the spoke 5, or leg, asthe case may be, the said tenon passing laterally through the side ofthe sleeve 2 and being housed within the same.

In the form ot the invention as illustrated in Fig. 2, a double-pointedscrew G is used as a dowel and is provided at an intermediate portionwith a surface 7 upon which a Wrench may be operated.

In the form ot the invention as illustrated in Fig. 3, the exterior ofthe sleeve 1 is provided With a volute corrugation Which is adapted tobecome embedded in the grain ofV the Wood and more firmly secure theparts together. In the form of the invention a doivel pin et isillustrated although a dowel screw may be employed if desired.

In the form or" the invention, as shown in Fig. ft, the sleeve 3 is usedtor the purpose of securing a tenon 8 to the piece 9. The screw 10 beingpassed through the tenon 8, the sleeve 3 and forced into the piece 9.The tenon 8 is then inserted in a mortise provided in the piece 10.

In the form of the invention as shown in Fig. 5, the sleeve l isillustrated as securing tvvo pieces ot ivood together' at a right angleto each other and a screw 1l is passed through one of the pieces and thesleeve into the other piece.

In the form of the invention as shown in Fig. (3, the sleeve 1 isembedded in the piece 12 which. is attached to the pieces 13 and 14 atthe point where they are drawn together. The screw 15 (indicated Ybydotted lines) passes through the slcevel andv is embedded `in the piecel2 and is located at the joint between the pieces 13 and 14 While thedovvel screw G holds the pieces 13 and 14 together'. The intermediateroughened portion 7 thereof may be used for affording surface for glueto adhere to the screw. i

In the Jform of the invention as shown in Fig. 7, the dowel pin e,passes through the tenen-16 which is located in the sleeve l and whichin Aturn holds together the Wooden I -Having described my invention whatI claim as new and desire to -secure by Letters- I Patent is A joint forwooden structure eomprisin uplposed pieces having mortses, n cylindricasleeve fittin snugly alon the entire length of the wa ls of the mortlsesand having internal beveled ends which are forced into the material ofthe pieces at the ends of the moitises, and a dowel member passing Icentrally and longitudinally through the l sleeve and being embedded inthe apposed l ture. Y

In testimony that I claim the. foregoing as my own, I have heretoaflixed my signature in the presence of two witnesses.
